BI Broadcaster, Scheduling Options and trigger using process chains

Hi,

In order to improve our current Broadcasted WorkBook delivery we would like to trigger the broadcast sending immediately at the end of data loading. Can anybody help with the step by step process on how to schedule the wookbook broadcast to send the data whenever there is a change in data and also trigger them by using process chains. How to parallelize via process chains?

Thanks in Advance!!!

Regards,

Lavanya.
